The identification of predictors of supragingival biofilm accumulation may improve the results of therapeutic strategies for dental caries and periodontal diseases in general clinical practice. This study aimed to determine predictors of changes in visible plaque (VP) and gingival bleeding (GB) during integrated dental care.
A retrospective longitudinal study was conducted by a census of patients receiving integrated dental care in a general clinical practice ambulatory at the Federal University of Rio Grande do Sul (Brazil). The sample comprised 91 charts of patients attended over a 6-months period. Gender, age, patient's main complaint, oral hygiene pattern, and clinical data were recorded from charts for the last two dental visits in the ambulatory. Changes in VP and GB were modeled by multiple linear regression and beta coefficients (b) were reported.
The mean follow-up time was 13 months. Significant reductions in VP (32.8 ± 27.9 to 17.4 ± 19.4%; p < 0.001) and GB (27.1 ± 23.8 to 18.5 ± 17.3%; p < 0.001) were observed. Higher plaque reductions were predicted by higher baseline VP levels (p = 0.02), shorter time (< 12 months) elapsed between VP recordings (b = 14.1%, p = 0.02), interproximal cleansing (b = 11.9%, p = 0.03), lower number of sessions for oral hygiene instruction (b = 13.7%, p = 0.02), and presence of pockets ≥ 6 mm (b = - 12.4%, p = 0.02). GB was predicted by time of follow-up > 12 months and baseline VP.
Plaque and gingivitis improved in patients under integrated dental care. Factors related to motivation, oral hygiene practices, and baseline periodontal status might be used as predictors of VP and GB changes.
Visible plaque and gingivitis reduced in a sample of patients treated under integrated dental care. Some predictors may determine for which patients the treatment may be maximize and those who will need greater efforts to achieve the therapeutic goal for oral hygiene.
预测龈上生物膜堆积的因素可能会改善一般临床实践中治疗龋齿和牙周病的治疗策略的效果。本研究旨在确定在综合牙科护理期间可见菌斑（VP）和牙龈出血（GB）变化的预测因素。
通过对在巴西联邦大学综合牙科诊所接受综合牙科护理的患者进行普查，进行了一项回顾性纵向研究。该样本包括在 6 个月期间就诊的 91 名患者的图表。从图表中记录了性别、年龄、患者主要主诉、口腔卫生习惯和临床数据，用于记录在诊所的最后两次就诊时的情况。通过多元线性回归和β系数（b）来模拟 VP 和 GB 的变化。
平均随访时间为 13 个月。观察到 VP（32.8±27.9 至 17.4±19.4%；p<0.001）和 GB（27.1±23.8 至 18.5±17.3%；p<0.001）显著降低。较高的 VP 基线水平（p=0.02）、VP 记录之间的较短时间间隔（b=14.1%，p=0.02）、邻面清洁（b=11.9%，p=0.03）、较低的口腔卫生指导次数（b=13.7%，p=0.02）和存在≥6mm 的牙周袋（b= -12.4%，p=0.02）预测 VP 降低更大。GB 由随访时间>12 个月和基线 VP 预测。
接受综合牙科护理的患者的菌斑和牙龈炎得到改善。与动机、口腔卫生习惯和基线牙周状况相关的因素可用作 VP 和 GB 变化的预测因素。
在接受综合牙科护理的患者样本中，可见菌斑和牙龈炎减少。一些预测因素可能决定哪些患者的治疗效果最佳，哪些患者需要更大的努力来实现口腔卫生的治疗目标。
